CARRIAGE-TOP JOINT.

SPECIFICATION forming part of Letters Patent No. 265,952, dated October 17, 1882.

Application filed August 30, 1882.

To all whom it may concern:

Be it known that I, NORMAN L. FoX, of Ueyion, in the county of Erie and State of Ohio, have invented a new and useful Improvement in Carriage-Top Joints, of which the followiug is a specification.

The object of my invention is to secure a reliable noiseless pivotal joint connection between the scat-rail and the bow of a carriagetop.

Heretofore the seat-rail and bow of carriagetop joints, so far as I am aware, have generally been formed by passing a headed screw-bolt through the main bow, which screw-bolt is an angular extension of the seat-rail, and applying a nut to the threaded end of'the screw-bolt. The difficulty with this class of carriage-top joints is that the operation of lowering and raising the top loosens the nut and causes rattling and liability of entire disconnection of the parts. My purpose is to overcome this difficulty, and 1 do it by screw-threading a bolthole through the seat-railand screwing the bolt into the screw-socket thus formed, and then firmly seating the'set-nut upon the threaded end of the bolt.

In the accompanying drawings, Figure 1 is a side elevation of a carriage-top. Fig. 2 is a larger side elevation of my improved carriagetopjoint; and Fig. 3 is a central section, partly in elevation, through thejoint.

-A indicates the seat-rail, the bolt-socket oi which is screw-threaded, as shown.

(No model.)

Bindicates the screw-bolt, provided with the ordinary bolt-head, 0, formed to receive a wrench, and 1) indicates the set-nut. The hole through the bow is not screw-threaded, and the bow works with sufiicient freedom in its motion to raise and lower the top between the head of the bolt and the carriage-rail in the usual way. With this construction, the bolthole through the seat-rail beingscrew-threaded to receive the bolt, there is much less liability of the bolt to be unscrewed and to get loose and cause rattling than usual, because the set nut clamps firmly down around the bolt against the seat-rail, and the screw-thread of the seatrail and nut, acting together, hold with great security.

Having thus described my improvement, what I claim, and desire to secure by Letters Patent, is-

The combination of the seat-rail having a screw-threaded bolt-hole, the bow, and the screwthreaded bolt and setnut, substantially as set forth.

In testimony whereof I have hereunto subscribed my name this 28th day of August, A. D. 1882.
